And: It may be not exactly what you want, but in case you are just looking for controlling fischertechnik models using a _powerful_ language and debugging environment, maybe you want to have a look at https://nanoframework.net/, that is, Visual Studio (or VS Code) and C# with nearly everything one might wish.

problem :my old pc sees the SD card portbut shows not a thick gray line whit part bluemy new pc sees no SD card port

i have SD formatter on my old pcit shows not any SD portalso when i push [refresh] noting happens

has anyone a idea how to solve this ?what do i not good ?

Hello,Do I understand correctly that you try to use the TXT as a card reader? You want to format the card while it is inserted in the TXT? If yes -> This is what you do not good. Remove the SD card and format it on your PC.Kind regardsPeter

https://github.com/fischertechnik/txt_demo_c_onlineHere you find information about the online programming possibilities of the TXT based on the normale fischertechnik firmware.The files are update and will work under 4.2.4. and 4.3.3.MS-Visual Studio 2017 community version.

python :if i have the firmwaremust i put it on the SD card as zip or unpacked ?can i use windows 10 for that or do i need a special programif so where do i find that ?

c++ :i have now eclipse [ java 8 ] on my new laptopi did not find a eclipse whit c++ AND javacan i instal a c++ eclipse next to a java eclipse ?[ i need java for my lego ev3 ]

Hi,good to hear that the SD cards are okay now.

Some thoughts:

-> there is no native C compiler on the TXT. You have to cross-compile on another CPU, may it be Linux or Windows. The best point to start is already linked above: https://github.com/fischertechnikAnyway I would not recommend starting with C...

The integration of the toolchain for cross compiling in Eclipse works very good.Eclipse is a very nice workbench.I not even notice that there is a crosscompiler involved.C/C++ is not so difficult to use. The main problem can be: understanding how the TA (transfer area) works.The advantage is that you can work with the normal TXT firmware.In one Eclipse workbench you can work with C/C++ and Java and other languages when they have their proper plugin available.

However there is a big difference between Eclipse and MS Visual Studio. In the MS-Visual Studio environment is .NET the base and the languages are dialects on top of the .NET framework.This makes it possible to work with a mix of dialects inside one aplication.

What about the power supply for your TXT? If you use a battery, please make sure that it is fully loaded.

according to the info i have to put the SD into the TXTand then use puttybut that gives a chicken vs egg problem :do i not need first to put the firmware on the SD ?

To boot the communitiy firmware, it has to be on the SD card. You have to download the CFW firmware and put it on your SD card using your PC (or whatever computer you use besides the TXT).We will update the documentation to make that step clear.

The documentation https://cfw.ftcommunity.de/ftcommunity-TXT/en/getting-started/installation.html says:"Download the latest version of the ftcommunity-TXT-firmware. At the time of writing this was “ftcommunity-txt-0.9.4.zip”. Copy all three files contained therein to the microSD-card (which should be formatted with FAT32. If you don’t know what that means and your card has 16GB or less: don’t worry, you’re set already)"This means for you: - Use the browser on your windows machine to download the file.- Save the zip file oy your computer and remember where you put it.- Unzip the file (see for example this instruction: https://support.microsoft.com/en-gb/help/4028088/windows-zip-and-unzip-files).- Copy all three files on your SD card.- Unmount the SD card on your computer and insert it into your TXT.

Dear blutatigro,did you successfully boot your TXT with the CFW (community firmware)?If yes, you can now proceed to program it in Python. For so beginning, I would usually suggest to use Brickly. However, if you need pure text programming, starting with Python is also possible. A detailed instruction in English can be found here: https://cfw.ftcommunity.de/ftcommunity-TXT/en/programming/python/tutorial-1.htmlIt's a lot of text to read, so you can avoid to "gamble". Just follow the instruction. If something is unclear, this forum will be able to help you.Best regardsEsther
